High-Frequency Performance
In 50
Ω systems, the ISL84467 has a -3dB bandwidth of
104MHz (see Figure 22). The frequency response is very
consistent over a wide V+ range, and for varying analog
signal levels.
An OFF switch acts like a capacitor and passes higher
frequencies with less attenuation, resulting in signal
feedthrough from a switch’s input to its output. Off isolation is
the resistance to this feedthrough, while crosstalk indicates
the amount of feedthrough from one switch to another.
Figure 23 details the high off isolation and crosstalk rejection
provided by this part. At 100kHz, off isolation is about 65dB
in 50
Ω systems, decreasing approximately 20dB per decade
as frequency increases. Higher load impedances decrease
off isolation and crosstalk rejection due to the voltage divider
action of the switch OFF impedance and the load
impedance.
Leakage Considerations
Reverse ESD protection diodes are internally connected
between each analog-signal pin and both V+ and GND. One of
these diodes conducts if any analog signal exceeds V+ or
GND.
Virtually all the analog leakage current comes from the ESD
diodes to V+ or GND. Although the ESD diodes on a given
signal pin are identical and therefore fairly well balanced,
they are reverse biased differently. Each is biased by either
V+ or GND and the analog signal. This means their leakages
will vary as the signal varies. The difference in the two diode
leakages to the V+ and GND pins constitutes the analog signal
path leakage current. All analog leakage current flows between
each pin and one of the supply terminals, not to the other
switch terminal. This is why both sides of a given switch can
show leakage currents of the same or opposite polarity.
There is no connection between the analog signal paths and
V+ or GND.
Typical Performance Curves TA = +25°C, unless otherwise specified.
